福寿草の芽伸びる from 庄内の日本桜草栽培日誌 (2012-4-4 12:00)

白い名札には『H10年種まき』と書いてあるのですが、
4月1日と4月3日の画像を見比べてみると、芽が伸びて、少し茂っているようです。
種から育てるのは初めてなので、芽吹いて2年目でどこまで育つのか興味津々です。(^^)

家族旅行 from 楽老 (2012-4-4 6:47)

　昨日の強風は午後9時半ごろから吹き荒れました。今朝もまだ吹いています。4月2日から1泊で伊香保温泉に出かけました。1月にも出かけましたので3か月ぶりです。倉渕の相間川温泉のふれあい館で昼食、せせらぎ公園で遊び榛名湖経由で伊香保温泉に向かいました。

桜草成育状況 from 庄内の日本桜草栽培日誌 (2012-4-4 6:00)

ウチで1年以上育てている桜草の中で、芽吹き具合が良いプランターを紹介します。
全体にまだこの程度ですが、庄内地方の野生品種『庄内』は頭すら覗かせていません。

八重咲き品種は毎年芽吹きが早く、もう少し芽を伸ばしています。
故斎藤教頭先生宅からの救助苗の芽吹き具合は、
今期絶対開花するであろう1番芽のみを植えているので、さすがに好調です。

Just a quick hello and a little info. I garden in the very West Midlands of the UK. Our area is very dry so most primulas are unhappy with the lack of

BHL and Our Users: Joachim Ladwig from Biodiversity Heritage Library (2012-4-3 21:57)

Today, we are excited to present Joachim Ladwig, a fossil collector in Germany with a passion for marine vertebrates. Though an amateur researcher, he has published a myriad of papers in amateur journals and holds among his repertoire of fossil finds the remains of a plesiosaur!

What is your title, institutional affiliation (or alternative place of employment), and area of interest?
I have no title or institutional affiliation! I work as a caretaker for a housing company in northern Germany and operate only as an amateur researcher.

I was born in 1962 and live in the federal state of Schleswig-Holstein. I’m a member of the “Gesellschaft für Geschiebekunde” (Society for Glacial Erratic Boulders), a cooperation of scientists (mainly from the Universities of Hamburg and Greifswald) and amateur collectors researching erratic boulders, which are the most important source of fossils in northern Germany.

How long have you been in your field of study?
I have been collecting fossils for more than 20 years. Soon after I began collecting, I undertook research (as an amateur) on fossil marine vertebrates, mainly from the Cretaceous period. One field of interest is sea-urchins, but I am especially interested in sharks and bony fish and their main fossil remains: teeth.

Some years ago I found the remains of a very great plesiosaur in a chalk-pit here in northern Germany. Since then I have been looking for literature on marine reptiles (mosasaurs and plesiosaurs), too.

When did you first discover BHL?
I think it was about 2 or 3 years ago, when I used Google to search for pdf-files of scientific papers on the internet.

What is your opinion of BHL and how has it impacted your research?
Because it was often very difficult to get old literature (and when you get it photocopied from your library the quality of the picture is miserable), it’s a great improvement to have access to pdf-files of these antique papers. To determine, for example, which species of fossil shark a find belongs to, it is necessary to take a look at the original descriptions. When you don’t have direct access to a university library, BHL is sometimes the only way to see these publications!

One concrete example: For 20 years I tried to find out which species the cow shark teeth in the northern German chalk belong toHexanchus microdonorHexanchus gracilis. In BHL I found the original papers in which these species where described. Now I am very sure of the identification: My fossil cow shark teeth belong toHexanchus microdon.

How often do you use BHL?
Several times a month.

How do you usually use BHL (read the titles online/download whole PDFs/Selecting Pages to Download for a custom PDF/Downloading High Resolution Images/Generating Taxonomic Bibliographies/etc.)
Generally, I download the whole pdf-file. I even print important papers. It’s not comfortable for me to read on the monitor; I prefer to read it on a piece of paper!

In the last years I have collected a whole hard-disk-drive of pdf files. They are not all from BHL, but many of the important and/or old ones are.

If you could change one thing about BHL, what would it be, or what developmental aspect would you like the BHL team to focus on next?
Very often I find that whole volumes of a journal are scanned as one file, but usually I only need one short paper. So I have to download an immense amount of data (806 pages!), while I cite only a small portion of it (for example, the work I cite in the next paragraph). It would be very useful to divide these big scans into smaller ones!

If you had to choose one title/item in BHL that has most impacted your research, or one item that you prefer above any other in BHL, what would it be and why?
I had looked for a long time for this paper:

“DAVIS, J.W. (1887): The fossil fishes of the Chalk of Mount Lebanon, in Syria. The Scientific Transactions of the Royal Dublin Society, 3 (Series 2): 457 - 636, Taf. 14 38; Dublin”

I found it at BHL.

It contains the original description ofHexanchus gracilis, a species of cow shark, which is often found in the upper cretaceous layers in northern Europe. I was trying to find out if it is a valid species or not. The plates in this work are very beautiful. They are not only of scientific interest, but are an art, too. I’m very pleased that I can use a reproduction from one of these plates for a planned publication.

Thank you, Joachim, for your contribution to the scientific realm and your willingness to share some of it with us! We are aware that article-level access to our content is a critical development for BHL, as it is one of our most user-requested improvements. We are currently working on models that will allow this level of access, but for the time-being you can find many BHL articles in our article repositoryCitebank.

Be sure to check out a bibliography of some of Joachim Ladwig's publications below. We're thrilled to know that BHL is helping him, and many others, identify and learn more about the fossilized remains of the magnificent biodiversity that lived ages ago.

兄からの電話 from 続・さくら草とメダカと山と渓流 (2012-4-3 17:17)

　久しぶりに兄からの電話。「オレさ～町会の役員をやめることにしたんだ」と兄。兄は町会の役員を２８年続けていることが自慢の種。兄の話によると病院で検査をした結果軽い「脳梗塞」を患ったあとが見られるといわれたというのだ。本人が気づかないうち発症してしまったらしい。自覚症状はなかったというがとにかく今後はストレスなど気をつけなくてはと思い町会の役員をやめることにしたというのだ。健康には人一倍気を遣っていた兄が軽いとはいえ脳梗塞とは・・・新聞（日本経済新聞３月１７日）には・・・脳梗塞は...
